integral from 3 to 4 of x^2+x-5

Solution

\int_{3}^{4} x^{2} + x - 5 d x

Solution

\frac{65}{6}

+1

Solution steps

\int_{3}^{4} x^{2} + x - 5 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{3}^{4} x^{2} d x + \int_{3}^{4} x d x - \int_{3}^{4} 5 d x

\int_{3}^{4} x^{2} d x = \frac{37}{3}

\int_{3}^{4} x d x = \frac{7}{2}

\int_{3}^{4} 5 d x = 5

= \frac{37}{3} + \frac{7}{2} - 5

Simplify

\frac{37}{3} + \frac{7}{2} - 5 : \frac{65}{6}

= \frac{65}{6}
